I need some help here. I know what I am doing with LSPDFR and I am relatively good with it even though i am pretty new. There is just one thing i am not sure of. If i have two different vehicles, and they both need carvariations mets installed or the lights do not work properly, but both metas need to be installed to the same place, how would I install it? Usually when I install one, one car works, then I install the other, that other car works and the first one does not anymore because the first one was overwritten. Been wondering this for a while but it hasnt really become something I need to fix until now.

The carvariations.meta file can easily support data on multiple vehicles. Just copy the lines for one vehicle and add them to the other file. You can't have two .meta files in the same folder. Just make sure to paste the lines in the right spot so that the entries (vehicle data lines) don't interfere with each other.
